ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wheel rim for heavy-duty automobiles or two-wheeled vehicles made of fiber-reinforced plastic (hereinafter referred to as FRP).
炭素繊維、ガラス繊維又はケブラー繊維（米国デ千ホン

の特徴かあり、軽量構造材として挿々の研究や実用化が
行なオつれている。Reinforcing fibers such as carbon fibers, glass fibers, or Kevlar fibers (product name of Desenhon Co., Ltd., USA), thermosetting resins such as Epoquin resin, polyester resin, or thermoplastic resins such as polyethersulfone resins and polysulfone resins. FRP impregnated with hardened and molded has: ■High strength and elastic modulus; ■Corrosion resistance against acids and alkalis; ■High fatigue strength; ■Good vibration damping properties; ■Light weight. Due to its characteristics such as , etc., it has been extensively researched and put into practical use as a lightweight structural material.
一方、燃料費低減の観点から自動上の軽量化が必要とさ
れているため、従来の鋼、アルミニウム、アルミニウム
合金等の金属製リムに代えて、これを上述のＦＲＰ製と
したリムに関する提案か従来から行なわれている。On the other hand, since automatic weight reduction is required from the perspective of reducing fuel costs, there is a proposal for a rim made of the above-mentioned FRP instead of the conventional metal rim made of steel, aluminum, aluminum alloy, etc. This has been done for a long time.
リムは第１図及び第２図にその代表例を示すように、フ

かった。The rim has a flange part 1, a bead seat part 2, and a drop center part 3, as shown in FIGS. 1 and 2.
and spoke attachment part 4 or wheel disc attachment part 4, and has a relatively complicated shape, so it is called FR.
When manufacturing by P, it is difficult to mold the long fibers along the shape because the shape has a large curvature between the 7 lunge part 1 and the bead seat part 2. Since it is not possible to orient the FRP rim, it has not been possible to manufacture an FRP rim with sufficient rigidity and strength.
そこで、上記の問題のない製法として、ｋ形状に沿いや

、ＦＲＰの軽量という特性が損われる欠点がある。Therefore, as a manufacturing method that does not have the above problems, SMC (5heet
FRP rims made from FRP (Molding Compound, a mixture for sheet molding) are known, but this rim has significantly lower strength and elastic modulus than FRP made from long fibers, so it is difficult to provide the same properties as metal rims. In order to achieve this, the thickness must be increased beyond a certain level, which has the disadvantage that the light weight characteristic of FRP is impaired.
そこで、この発明は長繊維を使用し、しかも繊維含有率
、剛性及び成形性に優れたＦＲＰ製リムを提供すること
を目的としている。Therefore, an object of the present invention is to provide an FRP rim that uses long fibers and has excellent fiber content, rigidity, and formability.

In the RP rim, sheets or tapes of a predetermined width woven from the above-mentioned reinforcing fibers are arranged along the axial direction of the rim and in close contact with each other in the circumferential direction, and the required number of sheets or tapes are laminated to have a uniform thickness to form a cylindrical lamination. The laminate is characterized by a structure in which continuous long fibers are wound in the circumferential direction of the laminate.

The above-mentioned laminate 6 consists of an inner layer 8 and an outer layer 8. Long fibers in the circumferential direction are impregnated with resin and wound around the outer periphery of the inner layer 8 in a bead sheet portion 9 to form an internal reinforcing layer 7. Similar long fibers are also wound around the outer periphery of the portion 10 to form an external reinforcing layer 7'.

繊維を組合せて使用することが有効である場合もある。The above-mentioned laminate 6 and reinforcing layers 7, 7 are formed on a male mold, and a female mold is fitted onto this and hardened by heating and pressurizing. However, if the axial rigidity is insufficient, the laminate Long fibers of reinforcing fibers may be placed along the sheet or tape 5 of 6. Furthermore, when carbon fiber is used as the reinforcing fiber, it has the advantage of being easy to impregnate with a resin, to be laminated, and to be easily molded due to the flexibility and ease of bending of the fiber. Furthermore, it may be effective to use a combination of two or more types of reinforcing fibers.

In particular, by providing a reinforcing layer, the overall rigidity increases and the K-shape can be easily created.
The effect of increasing the fiber content can also be achieved by tightening in the radial direction.
